Body not communicate with scan is250
I have a problem with my lexus is250 of the year 2007! the air conditioner does not work, it has gas and everything works but it does not turn on! and to check the problem I put the scanner and I can scan the engine, the transmission and the brakes but when I enter the body (BCM) it tells me that the connection was interrupted or a broken cable, that is to say that it does not communicate with the scanner. I need your help ! I already checked the fuses of the pilot and co-pilot and everything is fine! I put my scanner in another lexus and I could read perfectly the body control module could someone help me?
